Debugging Projects with the Adafruit CP2105 Friend
Adafruit has released a new hardware tool for embedded‑systems developers and electronics students: the Adafruit CP2105 Friend. This small breakout board works as a USB‑to‑dual‑UART serial converter, so you can hook up two separate serial ports at the same time using just one USB connection. It uses Silicon Labs’ CP2105 chip, which makes it easier to debug setups where several microcontrollers or peripheral devices need to talk to a host PC simultaneously. The board fits on a breadboard, so it can be dropped into quick‑prototype circuits without hassle.
Practical Applications for Engineering Students
Engineering students and hardware hobbyists often need several USB‑to‑TTL breakout boards to handle multiple serial links. This new board has two ports, so you can watch an ESP32 while programming an Arduino, or debug a sensor network with many nodes. Each port is an independent UART, letting you use one for fast data transfer and the other for command‑line debugging. The board cuts down on cable clutter and saves USB ports on laptops. In a lab, the dual channels are handy for testing master‑slave communication protocols because you can see both sides of the conversation at the same time, making firmware troubleshooting easier.
